ABSTRACT:
A process for preparing a continuous optical compensatory sheet has the continuous steps of: coating a liquid of a resin for forming an orientation layer in a solvent on a surface of a moving continuous transparent film; drying the coated layer to form a transparent resin layer; subjecting the transparent resin layer to rubbing treatment to give an orientation layer; coating a coating liquid of a discotic compound in a solvent on the orientation layer to form a coated layer; drying the coated layer; heating the coated layer to form a discotic nematic phase, whereby a layer of discotic compound is formed; and winding up the transparent film.
